We divide 358505 by 13
The aim is to understand the frequency of 13 in 358505.

Step 1:
13 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 13

On to step 2:
When dividing 35 by 13, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 26 from 35 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 13

Let's proceed to step 3:
When dividing 98 by 13, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 91 from 98 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 13

Advancing to step 4:
13 can be fit into 75 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 275.0
If we take 65 away from 75, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 13

On to step 5:
100 divided by 13 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 2757.0
If we take 91 away from 100, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 13

Let's proceed to step 6:
When dividing 95 by 13, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 27577.0
Subtract 91 from 95 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 13 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 27577.3
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 27577.3
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 27577.307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 27577.3076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 27577.30769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 27577.307692
Subtracting 26 from 30 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 13, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 27577.3076923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 27577.3076923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 27577.3076923, with a leftover of 1e-08.
